MODELING THE EFFECTS OF AREA CLOSURE AND TAX POLICIES: A SPATIAL-TEMPORAL MODEL OF THE HAWAII LONGLINE FISHERY
We develop an economic model for a multi-species fishery that incorporates the spatial and temporal distribution of effort and fish stocks. Catchability coefficients and initial stocks are estimated from catch and effort data for each specific location. Vessels are allocated over space and time to locations of maximum profit, which decline with harvest because of stock externalities. A supply function for labor allocation in the fishery is estimated. The simulated model is applied to the Hawaii longline fishery. The economic impacts of regulatory policies, such as reduction of inshore gear conflict and conservation of offshore turtle populations, are examined.Resource /Energy Economics and Policy,
Cultural Anthropology Through the Lens of Wikipedia - A Comparison of Historical Leadership Networks in the English, Chinese, Japanese and German Wikipedia
In this paper we study the differences in historical worldview between
Western and Eastern cultures, represented through the English, Chinese,
Japanese, and German Wikipedia. In particular, we analyze the historical
networks of the World's leaders since the beginning of written history,
comparing them in the four different Wikipedias.Comment: Proceedings of the 5th International Conference on Collaborative

The Shift from Centralized to Peer-to-Peer Communication in an Online Community: Participants as a Useful Aspect of Genre Analysis
In this paper we analyzed an online community based on a mailing list that was created as an internal marketing tool for launching a new network service. We focused on the change in communication over time among dispersed Sales representatives and the employees in a centralized Service Department. We conducted a genre analysis based on content (what), purpose (why), timing (when), form (how) and participants (who communicates to whom) (Yates and Orlikowski, 2002). Analyzing the participants in a genre and how those participants changed over time highlighted a shift from centralized to dispersed, peer-to-peer communication in this community. We highlight implications both for genre analysis and for organizational practice
The Role of an Online Community in Relation to Other Communication Channels in a Business Development Case
We investigated how sales representatives (Salespeople) and members of a service business
development department (the Service Dept.) communicated within an informal online
community, particularly in relation to their use of other informal and formal communication
channels. We found that while the Service Dept. developed formal communication channels
in order to fulfill the information needs of Sales, some types of information were apparently
more effectively provided by the online community. The result suggests that an online
community may play an important role both in making visible information needs, and in
providing information that can’t be better provided by the formal organization
Social capital increases efficiency of collaboration among Wikipedia editors
In this study we measure the impact of pre-existing social capital on the efficiency of collaboration among Wikipedia editors. To construct a social network among Wikipedians we look to mutual interaction on the user talk pages of Wikipedia editors. As our data set, we analyze the communication networks associated with 3085 featured articles – the articles of highest quality in the English Wikipedia, comparing it to the networks of 80154 articles of lower quality. As the metric to assess the quality of collaboration, we measure the time of quality promotion from when an article is started until it is promoted to featured article. The study finds that the higher pre-existing social capital of editors working on an article is, the faster the articles they work on reach higher quality status, such as featured articles. The more cohesive and more centralized the collaboration network, and the more network members were already collaborating before starting to work together on an article, the faster the article they work on will be promoted or featured
